摘　　要：在膜下滴灌条件下,研究不同灌水次数对日光温室辣椒土壤水分动态变化规律的影响。结果表明：随着灌水次数的增加,灌水间隔时间短,单次灌水量较少,对土壤水分的消耗逐渐减少,并且土壤贮水量变化的深度一般在0~100cm内,灌溉水基本能满足辣椒生长的需要;灌水次数越少土壤水分消耗得越多。The influence of different irrigation times on soil water dynamic change rule of greenhouse pepper under film mulched drip irrigation is studied in this paper.The result show that with the increase of irrigation times,the interval time and the irrigation quantity per time decrease,and the consumption of soil water gradually decreases.Moreover,the depth of soil water dynamics change under different treatments is 0~100 cm,the irrigation water can satisfy the need of greenhouse pepper.The more is the irrigation time,the more is the consumption of soil water.
